Example usage for android.nfc NdefRecord NdefRecord

Introduction

In this page you can find the example usage for android.nfc NdefRecord NdefRecord.

Prototype

public NdefRecord(short tnf, byte[] type, byte[] id, byte[] payload) 

Source Link

Document

Construct an NDEF Record from its component fields.

Recommend to use helpers such as {#createUri} or { #createExternal where possible, since they perform stricter validation that the record is correctly formatted as per NDEF specifications.

Usage

From source file:de.gadc.moneybeam.MoneyBeamActivity.java

/**
 * Creates a custom MIME type encapsulated in an NDEF record.
 * // ww w.  jav a2s .c om
 * @return the {@link NdefRecord} for usage in the {@link NdefMessage}
 */
public NdefRecord createMimeRecord(String mimeType, byte[] payload) {
    byte[] mimeBytes = mimeType.getBytes(Charset.forName("US-ASCII"));
    final NdefRecord mimeRecord = new NdefRecord(NdefRecord.TNF_MIME_MEDIA, mimeBytes, new byte[0], payload);
    return mimeRecord;
